Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478810, here are decompositions:

23 + 478787 = 478810
41 + 478769 = 478810
47 + 478763 = 478810
71 + 478739 = 478810
83 + 478727 = 478810
113 + 478697 = 478810
131 + 478679 = 478810
173 + 478637 = 478810

Showing the first eight; more decompositions exist.
